' understood upon reference to Fig. 2.

J denotes collars on side plates of the casing Q, and K suitable plates and bolts, whereby suitable packing means L for the shaft H may be adjusted.

M denotes arms on the projecting ends of the shaft H, extending down in the path of adjustable tappets N. It will be noticed that the tappets are arranged in elongated slots 0 in the pitmen F and that they are adapted to be secured to an adjustment by meansof headed bolts P and an exterior nut Q, as Will be The object of adjusting the tappets N isto regulate turning action imparted to the valveP through their contact with the arms M during operation of the pitmen F.

A receiving-chamber R is formed in the casing Q, having end port s S S and a like chamber T is formed in the casingat the opposite side of the valve P with end ports U U. Ports V l/V are provided leading to opposite ends of the cylinder R. The pipes O N lead into the valve P through ports A B and the ports S, S A B U, U V, and WV are respectively arranged for communication with recesses 1, 2, 3, and at in the valve P during operation thereof, as will appear further on.

C denotes a pipe leading from any suitable pressure-producing pump, (not shown,) and D a delivery or exhaust passage-way leading into a tank E The pressure-pump above referred to is made communicating with the tank E through means of suitable tubing The use of my invention will be understood from the following description: In the position of parts as illustratedfluid under pressure flowing through the pipe (J and into the chamber R will pass through the recess 1, port B down the pipe N, and thence into the upper end of the cylinder B above the piston C. The fluid being under pressure, obviously the piston C will be forced down ward and during its downward movement force fluid from the lower end of the cylinder B, up the pipe 0, through the port A recess3 in the valve, and through the port V, leading into the rear end of the cylinder R. It will be understood that the liquid now entering the cylinder B should be under sufflcient pressure to force the piston D forward, as indicated by the arrow, (see Fig. 3,) and thereby through the pistonrod C, cross-head B, and the pitmen F effect rotation of the fly-wheels W. I would here say that the valve P has an intermittent oscillating movement imparted through means of the tappets N contacting the arms M and that the tappets are spaced apart, so that the valve Will not be shifted until the piston D is near the end of its stroke and the pump-piston C is forced down to substantially the lower end of its cylinder B. When the valve P is shifted as just described, its recess 4 will be adjusted into registering position with the ports A? S and its recess 3 into register with the ports U V. At the same time the valverecess 2 will be adjusted into register with the ports 13 W. Now with the valve adjusted as just described obviously fluid under pressure in the chamber R will flow through the port S, recess 4:, port A, and down the pipe 0 to the under side of the pump-piston C, forcing it upward in reverse direction indicated by the arrow. During upward movement of the piston C the liquid being pumped will be drawn into the pipe J, as will be understood, and held therein by the check-valve K. It is apparent that when the valve P is adjusted from the position shown in Fig. 3, as last described, its recesses 4:, 3, and 2 will be in position providing for conveying pressure to the under side of the piston G and at the same time for exhaust from the rear end of the cylinder B through the port V, recess 3 in the valve P, the port U, chamber T, and the pipe D leading into the tank E Conjointly with the action of parts just described the liquid in the cylinder B above its piston G will be forced up the pipe N, through the port B the recess 2, port l/V, and into the cylinder R with pressure sufficient to force the piston D in opposite direction indicated by the arrow. Before the piston D reaches the end of its rearward stroke the arm M will be engaged by the approaching tappet, and thereby adjust the valve P back to the position shown in Fig. 3.

With the construction and arrangement of features above described and shown by my drawings the cylinder R, its piston D, the fly-wheels W, and their connecting devices provide a motor adapted for continuous intermittent operation of the valve P during flow of the operating fluid through the pipe It will be noticed that according to my invention the operating fluid after serving its use in working the pistons D C is discharged into a suitable receiver or tank E adapted to be conveyed back to the pressure-pump. (Not shown.)

Obviously a suitablyelevated source of liquid-supply could be employed instead of the pressure-pump above mentioned and in which case the liquid-power medium may be discharged upon the ground after serving its use.

It will be observed that my invention comprehends, in its broad conception, fluid-operated devices for lifting liquid; being the lifting-pump, a controller for the feed and exhaust of the fluid from the lifting means or pump; being the special valves and means operated by the feed and exhaust of the fluid from the lifting means whereby to shift the feed and exhaust controller.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an apparatus substantially as described, means for lifting liquid, fluid-oper- IIO ated devices for actuating said lifting means, a controller for the feed and exhaust of the fluid to the lifting means, and means operated by the exhaust of said fluid from the device which actuates the lifting means, whereby to shift'the said controller.

2. In an apparatus substantially as described, means for lifting liquid consisting of a pump, means conveying fluid under pressure to the lifting means, a controller for the i1 aid-conveying means operated by exhaust of the lifting means, and means which actuates the lifting means, whereby to shift the said controller.

3. In an apparatus substantially as described, the combination of a fluid lifting pump having a free piston, a tube carried by the piston having its ends extended through the pump-cylinder ends, feed and exhausting pipes leading into the pump-cylinder ends, \vherethrough to convey fluid under pressure, passage-'ways leading to and from the pump, wherethrough to convey the fluid being pumped, a controller in communication with the said feed and exhausting pipes, adapted to be shifted and thereby reverse action of the fluid flowing therethrough, and motor means adapted to shift the controller and reverse the action of the lifting means substantially as described.

4. The combination with a fluidlifting pump of the character described, of passage ways adapted for conveying fluid under pres- ROBERT H. RUSSELL.
